Found the solution. Might help someone. To save the current view as an image, do the following

UIGraphicsBeginImageContext(pictureView.bounds.size); 
                

[pictureView.layer renderInContext:UIGraphicsGetCurrentContext()]; 

UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();

UIImageWriteToSavedPhotosAlbum(viewImage, nil, nil, nil);
